The Lion's Courtship. Anna Kronberg & Sherlock Holmes Mysteries, #1

The illustrated prequel to the award-winning Kronberg & Holmes series. She saves lives. He takes them. In Victorian London's worst slum, they're about to collide. Anna Kronberg isn't your typical Victorian lady. She's a doctor disguised as a man by day, a nurse to prostitutes and criminals by night. When a sadistic gentleman starts carving up working girls, Anna teams up with Garret O'Hare, an Irish thief whose criminal connections are matched only by his dangerous charm.
Their uneasy partnership triggers something deadlier than either expected. The girl they're trying to save vanishes. Bodies start appearing in basements. And the killer has a new obsession: Anna herself. Some secrets are worth dying for. Others kill you first. Dark Victorian gothic meets edge-of-your-seat psychological thriller. For readers of Lyndsay Faye's The Gods of Gotham and Caleb Carr's The Alienist, who seek darker alternatives to Sherlock Holmes, and want their heroines unapologetically dangerous.
